SQ2308CES

Leiditech · MOSFETs · SOT-23

SQ2308CES from Leiditech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate; controls the channel, with VGS rated ±20V and RDS(ON) specified at VGS=10V and 4.5V.
2 S passive Source; the 3D view and symbol place it at the bottom-right lead, with continuous source current IS up to 2.3A.
3 D passive Drain; the single lead on the top side of the package, rated VDS=60V and ID=3.0A continuous at TA=25℃.
